如何在單引號中顯示雙引號PHP

Question

我有一個PHP echo語句：

echo "stores[".$row['BarID']."] = [". $row['BarName'] . ", " . $row['Address']. ",". $row['City']. "," . $row['State']. " 0". $row['ZipCode']. "," . $row['PhoneNumber']. ",". $row['Lattitude']. ",".$row['Longitude']. "]". ";<br>";  

輸出：

stores[0] = [The Ale 'N 'Wich Pub , 246 Hamilton St ,New Brunswick,NJ 08901,732-745-9496 ,40.4964198,-74.4561079];

但是我會像下面這樣在雙行中顯示輸出：

stores[0]=["The Ale 'N 'Wich Pub", "246 Hamilton St, New Brunswick, NJ 08901", "732-745-9496 Specialty: Sport", "40.4964198", "-74.4561079"];

我已經看過PHP網站上的《 PHP字符串函數手冊》，但仍然不了解如何實現它。 感謝您的幫助。

Answer 1

您錯過的關鍵字是“轉義”（請參閱Wiki ）。 最簡單的例子：

echo "\"";

將輸出：

"

編輯

基本解釋是-如果要將雙引號放在雙引號終止的字符串中，則必須將其轉義，否則會出現語法錯誤。

例：

echo "foo"bar";
         ^
         +- this terminates your string at that position so remaining bar"
            causes syntax error. 

為了避免這種情況，您需要轉義雙引號：

echo "foo\"bar";
         ^
         +- this means the NEXT character should be processed AS IS, w/o applying
            any special meaning to it, even if it normally has such. But now, it is
            stripped out of its power and it is just bare double quote.

因此，您（它是字符串的一部分，但您應該明白要點，然后自己做剩下的事情）：

 echo "stores[".$row['BarID']."] = [". $row['BarName'] . ", " . $row['Address'] .

應該：

 echo "stores[".$row['BarID']."] = [\"". $row['BarName'] . "\", \"" . $row['Address']. "\"

等等。
